UW-Madison Leads WI Charge Against Lake Michigan Plastic Pollution

The University of Wisconsin-Madison has launched a comprehensive research program targeting plastic pollution in Lake Michigan, partnering with local governments and coastal communities to stem waste from Wisconsin watersheds. Announced amid growing concerns over microplastics and debris, the effort builds on NOAA funding and aligns with broader Great Lakes restoration goals. Researchers like Haoran Wei and Mohan Qin in the Department of Civil and Environmental Engineering are quantifying microplastics in the lakes, a critical step for science-based management.[4][8] Wisconsin Sea Grant supports six UW-Madison projects out of 12 selected for $2.8 million in NOAA funding, enhancing understanding of Great Lakes contaminants including PFAS in groundwater.[3][4] Complementing UW-Madison's work, University of Wisconsin-Oshkosh researchers are installing Seabins—innovative plastic-capturing devices—at three Wisconsin Clean Marinas along Lake Michigan this fall. Funded by the NOAA Marine Debris Program and tied to the Great Lakes Plastic Cleanup, the project addresses an estimated 22 million pounds of plastic entering Great Lakes waters yearly.[1] UW-Oshkosh interns will monitor debris daily, characterizing pollution sources to inform prevention strategies, while fishing line recycling bins and a trash collection boat bolster marina efforts under the EPA Great Lakes Restoration Initiative.[1] These initiatives underscore Wisconsin's stake in the Great Lakes, which hold 95% of U.S. fresh surface water and border the state for 1,000 miles, sustaining 105 communities economically and recreationally.[4] Sea Grant researchers have developed filters to detect nanoplastics, vital as plastics bind contaminants threatening drinking and recreational waters.[7] Broader UW-Madison sustainability goals, announced by Chancellor Jennifer L. Mnookin on Feb. 8, include a new Sustainability Research Hub launching this spring to drive interdisciplinary grants on climate and pollution.[2][6]
